Every screen in this React Native app is streamed from the server as React Server Components (Flight / text/x-component). The Activity tab is a separate federated module loaded at runtime — and its Server Actions POST back to its own server. RSC + Module Federation on mobile. Built on Re.Pack @callstackio @repack_rn @reactnavigation @rspack_dev #react #reactnative

When the way software is built changes, we help companies adopt it. For over a decade, that meant bringing React Native to production across mobile, web, desktop, and TV. Now we are expanding that same mission to AI-native engineering: helping teams ship software with agents, safely and at scale. This is our new manifesto.

I just released fast-flow-transform 🚀 If Flow is the last thing keeping Babel in your pipeline, this is for you. It strips Flow syntax natively, so the rest of your pipeline can stay on newer tooling built around SWC or Oxc. Published benchmark: ~20x faster than Babel.

Been working on adding @repack_rn support to React Native @storybookjs and the first working version is in v10.2.2-alpha.3 🎉 Use the Storybook plugin to handle configuration, and the agent setup skill now knows how to configure Repack projects too.

🚨 If you're using babel-swc-loader, you should consider upgrading to newly released Re.Pack 5.2.3 We fixed the configuration handoff for transform-react-jsx from Babel to SWC, resolving compatibility issues with libraries like NativeWind. Release notes: github.com/callstack/repack/…

In Re.Pack 5.2.1, when using babel-swc-loader, we fixed determining the correct module type: SWC now inherits it from Babel. We've also fixed Module Federation emitting unnecessary chunks in production, making the final output smaller 🚀 Release notes: github.com/callstack/repack/…

Just resolved an issue where the new babel-swc-loader in @repack_rn was performing poorly. From 115.4s → 2.6s 🔥 Turns out it was a 100k+ lines prebundled lib that was getting processed by a single Babel worker 🤯 Delegating this to @swc_rs decreased the build time 40x!
